v Application M ns 16, 193:, Serial No. 590.211 7 Claims. (01. 200-50) This invention relates to a package for rolled goods. It relates specifically to a package for rugs or'other surface covering of the felt base type, although it may be used with advantage in packaging any rolled article. Rugs of the felt base type comprise a sheet of felt saturated with asphalt or any suitable saturant, and generally have a decorative design printed on one face thereof. Heretofore, in packaging rugs of this type it has been necessary to roll said rugs on a comparatively large diameter and then cover the rolled rug with an outer wrapper of paper. The rugs can not be' rolled on a small diameter because of the susceptibility of the felt and the l5 paint to cracking. in cases of felt of inferior quality itwas necessary to increase the size of the roll even more than usual. This added the disadvantage of non-uniform size to the other disadvantages of the completed packages.

It is well known that rugs of the linoleum and felt base type will vary in axial length when rolled due to irregularities caused in part by trimming of the selvage from the edge of the iugs. While this variation is not generally great,

most rugs of a given standard size will vary somewhat from' that size when rolled. For example,

a 9 x 12 rug may have an axial length when rolled of 9'- while another rug of the same standard size (9 x 12) may have an axial length when rolled of 9' or 9'-%". In other words, the axial length of the rugs in any standard size is indefinite due toirregularities.

It has been proposed to package rugs of this type in paper board tubes provided with wooden 35 end disks. When this type of package is used,

the two tube sections are preformed and are fitted over the rug and a securing tape attached to the abutting tube sections. This necessitates that the tubes be of a combined length sufficient to ac- 40 commodate the maximum oversized rug and as a consequence a rug having a lesser axial length than the maximum is free to move longitudinally of the tubes, or to telescope within the tubes thus causing marring of the surface. If the package 45 is dropped on end from any appreciable height, for example in unloading cars, the impact caused by the rug moving longitudinally of the tube is often su'fiicient to rupture the tube, and breaking out the disk and damaging the rug.

50 It is an object of. my invention to provide a rug package that will have a neat appearance, will be durable, and 'will protect the rug from injury during transit. It is a further object of my invention to provide a rug package that may 55 be produced at a moderate cost. Other objects of my invention will become apparent upon reading the annexed specification taken in connection with the accompanying drawings, in which;

Figure 1 is an assembly layout, in diagrammatic form, of an apparatus which may be used 5 tocarryoutmymethod; I

Figure 2 is a perspective view of my complete package; and

Figure 3 is a fragmentary perspective view of one end of my completed rug package.

In Figure 1, the reference numeral 2 indicates an inspection table upon which a plurality of felt base rugs or other articles, not shown, to be packaged are stacked. The rugs are passed individually through a trademarkingmachine 3 which 5 prints suitable indicia on the bottom surface of the rug. A belt conveyor 4 moving ovena pair of rolls 5 and 6 carries individual rugs from the trademarking machine to a pair of pinch rolls 1 and 8. The pinch rolls 1 and 8 are effective to 20 v move the rug through a conditioning chamber 9.

The conditioning chamber is particularly adapted to aid in packaging rugs when the temperature in the room is so low that the rugs are too stiff to be bent easily. The conditioning chamber is 25' heated by steam or any other suitable means so that the rugs passing through the chamber may be heated to approximately 100 F. The amount of heat applied to the conditioning chamber will depend upon the outside temperature.

The rug passes from the conditioning chamber 9 to a roll-up device II) which consists of a suitable frame I I in which are mounted an upper roll l2 and two lower rolls l3 and H. The roll I2 is raised and a thin wooden core is placed between the rolls l3 and H. The roll I! is then lowered so that it rides on top of the core. The end of the rug to be rolled is secured to the core by means of a fabric apron and the rolls l3 and H are driven in a counter-clockwise direction, asviewed in Figure 1. The roll H, which rests on top ofthe core, is an idler.

When the rug has been rolled up it is moved out of the roll-up machine by a rug expelling device ii. The rug expelling device includes a pair of belt conveyors l6 and I1 disposed one above the other with a space therebetween suiiicient to accommodate a rolled rug and to maintain it under slight compression so as to prevent unrolling. The conveyors l6 and I1 move the rolled rug on to a plate ll. A pair of spring clamps l9 engage opposite ends of the rolled rug to prevent it from unrolling while a tube is beingplaced thereover.

I prefer to package the rolledrug in a paper tube 20 formed in two sections. One section of I the'tube when the out injuring th suitable tube may b because of the packaged rug during shipment. and subse-' quent handling operations. After the tube has been placed around the rolled 2|, the tend-.- ency of the mg to unroll'. cause s the rug to expand-slightly'and to press against the walls of the tube. After this expansion the mandrel upon which the rug has been rolled is removed and :a

plywood disk 22 is placed in each end of the tube. These disks are provided with a small hole 22' in the center thereof to allow the escape of air in disks are pressed flush against "the ends of the rug.

The rolled rug 2| now confined in its tube 20 is placed in a centering machine 23. The centering machine comprises a pair of centering heads 24' that are moved into the open ends of the tube 20 to press the disks 22 flush against the ends of the rug 2| and to center the rolled rug in the tube. The centering heads 2| are rotatable, so when the tube is supported thereon a strip 25 of adhesive paper or any similar material may be applied over the joint between the sections of the tube;

The tube and-its rolled rug crimping machine 28. The crimping machine includes a pair of crimping heads 21 adapted to engage the ends of wardly into beads or flanges as indicated generally at 28, Figure 3. The ends of the paper tube are oiled prior to use to lubricate them, so that the ends may be turned inwardly without'breaking or burning. The ends of the tube are turned inwardly and'the crimping heads working simultaneously against the opposite ends of the tube force the ends against the disks 22. The crimp- 'ing action may be continued for an instant after the ends of the tube are pressed flush against the disks. This extra pressure results in the formation of a groove or depression 29 in the bead or flange 28. The groove 29 has a reinforcing eifect on the end of the tube and adds greatly to the rigidity of the package. The combination of the disk 22 and the inwardly crimped or, beaded portion 28 of the tube forms a rigid end structure. which serves to retain the rug in position within the tube. The entire package structure is sufliciently rigid so that the rug can not move within the tube.

The apparatus described herein for packaging rolled articles is more completely illustrated and described in my joint copending application with Benjamin F. Ken and Fred G. Rottmund, Serial 'No. 599,216, flied March 16, 1932 and the method is described and claimed in my copending appli-'- cation, Serial No. 736,683, flledJuly 24, 1934, as a division of this application.

Although I have described my article in considerable detail, it will be understood that various features may be modified without departing from the spirit or scope 1y, I do not desire details described except pended claims. Iclaim:
